Differentiate log(1 + x2) with respect to tan–1x.
Let u = log(1 + x2) and v = tan–1x.
We need to differentiate u with respect to v that is find.
On differentiating u with respect to x, we get
[using chain rule]
However, and derivative of a constant is 0.
Now, on differentiating v with respect to x, we get
